| Study Title | Untargeted metabolomics of Quercus ilex acorns |
| Study Type | LC-MSE analysis |
| Study Summary | UPLC-MSE analysis of samples from Quercus ilex acorns flour. The objective of the study is to obtain a metabolomic profile of several acorns from different trees. This phytochemical analysis and characterization will be a base for the identification of bioactive, antinutritional, or toxic compounds and traceability analysis. |

Sample Preparation:
| Sampleprep ID: | SP001453 |
| Sampleprep Summary: | Metabolites were extracted from acorn flour as described by Valledor et al., (2014), with minor modifications. 600 µL of ice-cold methanol: chloroform: water (5:2:2) was added to 50 mg of acorn flour, mixed by vortexing, and the mixture sonicated (ultrasonic bath, 40 kHZ for 10 min). After centrifugation (4 oC, 4 min, 20,000 × g), the pellet was once more extracted with 200 µL of cold methanol: chloroform: water (5:2:2). The two supernatants were combined and vacuum dried at 30 oC (Speedvac, Eppendorf Vacuum Concentrator Plus/5301). Dried extracts were reconstituted in methanol, centrifuged at 20,000 × g for 10 min, filtered through 0.22 µm PTPE membranes (Thermo Scientific, MA, USA) and filtrate collected in 1.5 mL LC/MS certified sample vials. |
